急性透壁心肌梗死所致的心外膜交感神经纤维受损,被认为在梗死后室性心律失常的发生中起作用。本研究采用正电子发射体层照相术(PET)技术,利用[18F]-6-荧光多巴胺和[13N]-氨分别测定急性Q波型心肌梗死后从2周到6个月期间,梗死局部心肌血流量及交感神经支配修复。研究10例病人(
Impairment of the epicardial sympathetic nerve fibers caused by acute transmural myocardial infarction is believed to play a role in the occurrence of ventricular arrhythmias after infarction. In this study, Positron Emission Tomography (PET) was used to measure the regional myocardial infarction after acute Q wave myocardial infarction from 2 weeks to 6 months with [18F] -6-fluoropamine and [13N] Blood flow and sympathetic repair. Study 10 patients (
